Digital sculpting can create photorealistic 3d models used in still imagery. A procedurally generated photorealistic landscape created with Tarragon. Tarragon has been used in creating CGI for movies.
There are two main paradigms in computer generated imagery.[citation needed] The simplest is 2D computer graphics which reflect how you might draw using a pencil and a piece of paper. In this case, however, the image is on the computer screen and the instrument you draw with might be a tablet stylus or a mouse.
What is generated on your screen might appear to be drawn with a pencil, pen or paintbrush. The second kind is 3D computer graphics, where the screen becomes a window into a virtual environment, where you arrange objects to be “photographed” by the computer.
Digital installation art constitutes a broad field of activity and incorporates many forms. Some resemble video installations, particularly large scale works involving projections and live video capture. By using projection techniques that enhance an audience’s impression of sensory envelopment, many digital installations attempt to create immersive environments. Others go even further and attempt to facilitate a complete immersion in virtual realms. This type of installation is generally site specific, scalable, and without fixed dimensionality, meaning it can be reconfigured to accommodate different presentation spaces.
